Detailed Description

Class for scanning a region given by a line and a distance ca.

perpendicular to the line GetNext() return on successive calls all image coordinates within +-epsilon from line given by start and end Fast implementation based on Bresenhams algorithm

Note
This is the old ScanLine2 class replacing ScanLine.
